I really don’t think cancelling a deal that the other side was not and never intended to keep is a bad thing.
Clinton collected a big bag of empty promises from N. Korea. He certainly looks successful, holding all that fools gold.
Sure, North Korea temporarily halted their plutonium program. At the same time they became involved in a secret uranium project with the AG Kahn network. Nice bait and switch behind Clinton’s back (or more likely, right in front of his nose).
